Mention has been made of the towns which the Spaniards came to in the course of their marchings up and down the country. Men had told them, in all soberness, that far away in the north-west seven flourishing cities,[1] wondrous great and rich, lay hid among the mountains. We remember that their first expeditions were planned to reach these seven cities. Now, when, at last, the Spaniards did come to them, these wonderful cities proved to be large, but not rich, full of people, though by no means such as the white men expected to see there. Though sorely vexed to think they had come so far to find so little, the Spaniards were very much astonished by the appearance of these cities, the like of which they had never seen before. So these cities hid away among desert mountains were long remembered and often talked about. But these cities were not cities at all, as the term is now understood. Instead of many houses spread out over much ground, the builders plainly aimed at putting a great many people into a little space. Yet the cities they built were neither simply walled towns, nor simply fortresses, but a skilful combination of both. In the open plain they commonly consisted of one great structure either enclosed by a high wall, or else so built round it that wall and building were one. On the other hand, if the pueblo[2] stood upon a height, the houses would be built all in blocks, and have streets running through them, though in other respects the manner of building was everywhere the same. In either case, this style of architecture made them look less like the peaceful abodes of peaceful men, than the strongholds of a warlike and predatory race, whence the inmates might sally forth upon their weaker neighbors, just as the lords of feudal times did from the rock-built castles of the Rhine. It is plain they had grown up out of the necessity for defence, as every thing else was sacrificed to its demands, and we know that necessity is the mother of invention. The single great house, in which all the inhabitants lived together, is perhaps the most curious. Let us suppose this to be a three-story building, parted off into from sixty to a hundred little rooms, with something like a thousand people living in it. Could the outer wall be taken away, the whole edifice would look like a monstrous honeycomb, and in fact the pueblo was nothing else than a human hive, as we shall presently see.
